The short tale about ASAT anti-satellite weapons.


Kimmo Huosionmaa

The developing ASAT-weapons is a little-known thing in space programs. The newest technology is actually developed for microwave bombs, which would destroy the targets very sharply. The systems are acting different ways but the main idea is to terminate the satellite by using the method, which keeps its core in one piece. That eliminates the debris from that trajectory, and it would save the own satellites from the damages. In the 1960s there were testing the nuclear weapons, which will make all satellites, what is at the orbiting trajectory unable to operate, but the problems of the plasma caused that this kind of weapons was not created, because they would destroy both side satellites, and that would mean end of the GPS systems and other things.

The developing the anti-satellite weapons have been beginning from the cold-war era. During that time there were made ASAT test by the Soviet Union and the USA by using kinetic energy weapons, what based satellites, that were collated with together. And some experiments were made by using machine guns and that kind of things. The recoilless weapons like bazookas and other kinds of things are also tested because the recoil of the machine guns are causing that the trajectory of the satellite would be disturbed.

And that's is a very problematic thing in ASAT missions. One of the most interesting things about the weapons that are developed for the killer satellites is a so-called centrifuge gun, what will be the rotating layer, where is dropped the metal balls. The layer would throw the metal ball with speed, which is the same as the layer will rotate. This kind of weapons is very interesting because they would be installed in the other satellites and use for the self-defense systems. Another very interesting solution would be the "Trophy" system, what is installed in the tanks, and this system can be used in the satellites as the rotating gun turret, what will destroy incoming objects and also it can be used in the offensive purposes.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
